Herstellung von Betonschwellen für Eisenbahnschienen

摘要

According to a first aspect of the invention, a positioning and/or holding force is applied on a section of at least one holding element that is to be embedded into the concrete tie, said section projecting outwardly through a respective opening of the wall of a tie mold. According to a second aspect, the tie is partially removed from the mold before it is completely hardened so that at least one wall section of the mold (26) that is provided with at least one receiving opening for a respective holding element remains in the tie together with the holding element while a remaining mold (23) is removed from the tie. The at least one wall section of the mold (26) is removed from the tie later once the tie (10) has further hardened and the at least one holding element remains in the tie. According to a third aspect of the invention, the tie (10) is at least partially taken out from the mold before the tie is completely hardened and at least two tie holding elements are corrected with regard to their desired relative position before the concrete is completely hardened.
